Blum is never a disappoint.
If screws on your hinges are elevated at all these are useless. Better off to just replace your hinge with a true soft close hinge. These are cheap.
It’s important to install the soft close on whichever hinge is least likely to be bumped. If you’re lucky enough to have blum hinges and you get the right size of soft-close attachments, installation is literally just a snap.
Once installed they look bulky and yes they do dampen but there's no way to adjust. If they are bumped they will fall off and you will find yourself often having to refasten them.
